How to build Powerpc crosstools on Arch

needed GPG keys for linux, patch and glibc headers:

These tools are 32bit, and for Powerpc G5 we need 64bits. And browsing the Arch forums... yeah, general public intrests.... they go with the dodo. Lets make our own Distro, with Doom and Anime... I mean documentries on space and sciense.

64bit

Testing the compiler

Write a file containing:

#include<stdio.h>

int main () {
        printf("Hello PowerPC!\n");
        return 0;
}
powerpc-linux-gnu-gcc -static -g hello.cpp -o hello 
qemu-ppc hello

Building bare kernel

this is work in progress

git clone https://github.com/raspberrypi/linux raspberrypi-linux
cd raspberrypi-linux
cp arch/arm/configs/bcmrpi_cutdown_defconfig .config
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- oldconfig
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- menuconfig
make ARCH=arm CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- -k

or do some defconfig for ppc

make -j 4 [u|z]Image dtbs modules
make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
export ARCH:=arm
export CROSS_COMPILE:=arm-none-linux-gnueabi-


ARCH=arm
COMPILER=arm-none-linux-gnueabi
obj-m := Hello.o
KERNELDIR := /home/ravi/workspace/hawk/linux-omapl1
PWD := $(shell pwd)
default:
    $(MAKE) -C $(KERNELDIR) M=$(PWD) ARCH=$(ARCH) CROSS_COMPILE=$(COMPILER) modules

clean:
    $(MAKE) -C $(KERNELDIR) M=$(PWD) ARCH=$(ARCH) clean
    
    
ARCH := arm
CROSS_COMPILE := arm-none-linux-gnueabi-
obj-m := Hello.o
KDIR := /home/ravi/workspace/hawk/linux-omapl1
PWD := $(shell pwd)
export
default:
          $(MAKE) -C $(KDIR) M=$(PWD) modules
clean:
          $(MAKE) -C $(KDIR) M=$(PWD) clean

a device tree database is required for proper functioning arm targets, for my example ive used versatile-pb.dtb that is also provided after compiling the kernel.
